Jupiter LV, provisionally known as S/2003 J 18, is a natural satellite of Jupiter. It was discovered by a team of astronomers led by Brett J. Gladman in 2003.
Jupiter LV is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 20.220 Gm in 604.99 days, at an inclination of 143° to the ecliptic (145° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.0509.
It belongs to the Ananke group, retrograde irregular moons that orbit Jupiter between 22.8 and 24.1 Gm, at inclinations of roughly 150-155°.
The moon was lost following its discovery in 2003. It was recovered in 2017 and given its permanent designation that year.

We likely have all of the lost moons in our new observations from 2017, but to link them back to the remaining lost 2003 objects requires more observations a year later to confirm the linkages, which will not happen until early 2018. ... There are likely a few more new moons as well in our 2017 observations, but we need to reobserve them in 2018 to determine which of the discoveries are new and which are lost 2003 moons.
